ocfs2: Increase max links count
Since we've now got a directory format capable of handling a large number of entries, we can increase the maximum link count supported. This only gets increased if the directory indexing feature is turned on. Signed-off-by: Mark Fasheh <mfasheh@suse.com> Acked-by: Joel Becker <joel.becker@oracle.com>
